摘要
在电磁波波动方程WKB法近似解基础上,应用电磁波能量衰减计算方程,分析了电磁波在火箭尾焰中的传播与受干扰过程,研究了等离子体频率、自由电子碰撞频率和自由电子密度等火箭尾焰电磁特性参数对电磁波能量衰减特性的影响。结果表明,电磁波频率和尾焰电磁特性共同影响电磁波的衰减。
On the bases of WKB approximate method solution of electromagnetic wave equation the characteristics of the rocket wake flame interference are calculated and analyzed. The electromagnetic interference of the rocket wake flame electromagnetic parameters including plasma frequency, electron collision frequency and electron density are calculated and analyzed. The results show that the attenuation of the electromagnetic signals are decided by both of the frequency of the electromagnetic wave and the electromagnetic characteristics of rocket wake flame.
